What is a Smart EV Charger?
A smart EV charger is an advanced electric vehicle charging station equipped with communication and data processing capabilities.
In a Smart EV Charging environment, the EV, the smart car charger, the Charge Point Management System (CPMS), and the utility network constantly communicate.
This communication enables enhanced functionality, efficiency, and convenience compared to conventional non-smart chargers.
It connects to the internet and communicates with devices such as smartphones, home energy management systems, and utility networks.
Smart EV Chargers perform intelligent charging management and offer seamless grid integration.
This allows remote monitoring and control, integration with renewable energy sources, participation in demand response programs, and an overall optimized charging experience for electric vehicle owners.
EV Smart Charger is becoming increasingly important and mandatory in some cases worldwide.
Smart vs. Non-Smart EV Charger
When comparing Smart EV Chargers to Non-Smart EV Chargers, it becomes evident that non-smart chargers are increasingly inadequate according to today’s standards.
As mentioned, while non-smart chargers simply provide electricity to charge an electric vehicle, smart chargers offer connectivity and enhanced functionality, efficiency, and convenience.
Most importantly, smart chargers contribute to grid stability and environmental sustainability.
As electric vehicle adoption accelerates and energy management becomes more crucial, non-smart chargers fall short of meeting EV owners’ and utilities’ evolving needs and expectations.
That is why various countries are making Smart car chargers mandatory.
On the forefront is the UK, where all EV chargers sold for domestic or workplace use after June of 2022 must now have smart charge functionality.
What Makes an EV Charger Smart?
An EV charger is considered smart when it possesses advanced features and functionalities that go beyond the basic task of charging an electric vehicle.
However, a charger is not smart by itself. It’s just a piece of charging hardware.
What makes a Smart EV charger smart is its ability to connect to the car and the smart EV charging software.
The smart EV charging software or platform is a critical component of a Smart EV Charging technology responsible for managing and optimizing the charging process.
It serves as the interface between the charger, the electric vehicle, and external systems such as utility networks, home energy management systems, and user devices like smartphones.
Smart EV Charging: Unlocking Its Full Potential
The software processes real-time data from the grid, the charger, and the vehicle to facilitate intelligent charging management.
By analyzing collected data on energy usage, charging habits, and other relevant metrics, the smart EV charging software manages the charger and charging.
How does EV Smart Charger work?
An EV Smart Charger works by combining advanced hardware and software components to deliver an optimized and efficient charging experience.
At the hardware level, the charger is equipped with communication modules (Wi-Fi, Ethernet, cellular connectivity,…), enabling it to connect to the internet and interact with external devices and systems.
The charger’s software processes real-time data from the grid, the vehicle, and user preferences to manage the charging process intelligently.
This includes adjusting charging rates based on available electrical capacity (load balancing), responding to grid conditions (demand response), and integrating with renewable energy sources.
Communication protocols, such as OCPP and ISO 15188, facilitate seamless interaction between the charger, the vehicle, and the backend systems.
This combination of hardware and software allows the smart charger to deliver a highly efficient, convenient, and sustainable charging experience for electric vehicle owners.
Key Features of a Smart EV Charger
As established, smart EV chargers offer advanced charging features, so let’s look at the key ones.
Connectivity
Smart EV chargers communicate with other devices and systems, such as the central EV Charging software, utility networks, home energy management systems, and smartphones.
Intelligent Charging Management
Intelligent Charging Management or dynamic load management describes when smart chargers optimize charging sessions based on user preferences, electricity rates, and grid conditions. By doing so, they ensure efficient energy use and minimize costs.
Load Balancing
With dynamic load balancing, the charger adjusts charging rates based on the available electrical capacity. It prevents overloading the electrical infrastructure and ensures a safe and efficient charging experience.
Demand Response
Smart EV chargers can participate in demand response programs. Adjusting charging rates in response to real-time grid conditions contributes to grid stability.
Renewable Energy Integration
Home solar panels or other renewable energy sources allow EV owners to charge their vehicles with clean, green energy and further reduce their environmental impact. Smart EV Chargers are the ones that manage this integration.
Remote Monitoring and Control
Smart chargers can be remotely monitored and controlled. Therefore, users can schedule charging sessions, set preferences, and receive notifications.
Data Collection and Analysis
The data on charging habits, energy usage, and other relevant metrics are collected and analyzed to optimize charging schedules and provide insights into EV charging behavior and trends.
Billing and Payment Processing
Smart charging solutions allow charging providers to perform EV charging billing and payment processing.
With support for different business models and payment methods, it makes the charging process more convenient for users and more profitable for charging station owners.
These features enable Smart EV Chargers to offer greater efficiency, convenience, and sustainability for electric vehicle owners and utilities alike.
Types of Smart EV Chargers
In general, smart EV chargers fall into three categories:
- Smart EV chargers for personal use or use in multi-tenant buildings.
- EV Smart Chargers for Companies for charging employees’ EVs and companies’ EV fleets.
- Public Smart Car Chargers for commercial charging.
Smart EV Home Charger
Charging at home is the predominant solution for charging electric vehicles.
In fact, many studies have shown that EV drivers who are also homeowners do about 80% of their charging at home.
According to Juniper Research, by 2026, around 35 million home chargers will be installed globally.
A smart EV home charger uses dynamic load balancing that balances the energy usage of the electric vehicle and other appliances in the home grid.
It also enables remote monitoring and scheduling, while more advanced functions are usually left out.
When an EV is connected, the software will distribute the power to the devices that currently need it most.
Doing so will prevent overloads and only charge the vehicle when it’s most energy and cost-efficient.
Smart EV home chargers can also optimize charging from the grid in combination with solar panels or other renewable sources.
These kinds of Smart chargers are often used also for smaller multiapartment buildings or parking garages.
EV Smart Chargers for Companies
Many companies started installing charging stations or applying EV Charging as a Service.
Besides allowing their employees to charge electric cars while at work, the real need for smart chargers lies in the electrification of companies’ fleets.
Smart car chargers are essential for EV fleet management and managing that all fleet EVs charge at the right time, for the right price, and in the correct order.
Public Smart Car Chargers
Public chargers are the ones that will decide the future of electric cars and the e-mobility revolution.
If we look at recent electric car sales statistics, public charging stations will be in high demand if we want to switch to electric vehicles successfully.
It’s safe to assume that with this amount of charging happening at public charging stations, they will need to be smart, not just fast.
